Isso mesmo Ivan,
Várias vezes as informações que pedia não constavam nos arquivos .HTML; demorei para entender que o conteúdo do .CSV sempre seria mais preciso. Para abrí-lo, basta dragá-lo em um programa de planilhas (como o Excel) e ajustar suas colunas para a vizualização.
Atenciosamente,

The report in the html file looks incorrect.

If you check "DesignSpecification:OutdoorAir", the outdoor air flow is specified, but, when simulate, the output show zero outdoor air (in outdoor air summary) in all zones.

Hi everyone,
I have a problem a long time and I can not solve.
All VRF systems have the output with external air flow zero. I do not know what the problem is.
I used the example file VariableRefrigerantFlow_5Zone.idf, and even then the outside air is zero.
Does anyone know the source of the problem?
Thanks!Técg. Ivan Mezzacapa
